Product Details

NTN Japan-Made High-Precision Cylindrical Roller Bearings (NUP2328EM Series)

Description Key Highlights
Model & Precision NUP2328EM, P0–P2 precision grades — ultra-low vibration (Z1V1 to Z3V3), ideal for high-speed spindles
Dimension & Structure 130×280×93 mm, cylindrical non-aligning design with separable rings for easy mounting
Material & Durability High-carbon chromium bearing steel (JIS SUJ2), heat-treated for >2M hrs L10 life
Load Capacity Optimized radial load handling — 30% higher dynamic rating vs. standard ISO 281 bearings
Lubrication Flexibility Compatible with both grease and oil — pre-lubricated options available for maintenance-free operation
Origin & Standards Manufactured in Japan under NTN’s strict JIS B 1514-1 quality control; compliant with ISO 15, ABEC-1 to ABEC-9
Applications Industrial gearboxes, wind turbine main shafts, CNC machine tool spindles, rolling mill stands
Differentiation vs. Competitors EM (Electric Motor) series: lower noise, tighter internal clearance control, and superior cage guidance vs. generic N2328 or NU2328
Quality Assurance 100% dimensional inspection, ultrasonic flaw detection, and batch traceability (QR-coded packaging)
FAQ Q: Is this interchangeable with SKF NJ2328E? A: Yes — identical boundary dimensions and load ratings; NTN EM-series offers enhanced thermal stability. Q: Can it replace older NUP2328? A: Yes — same interchangeability per ISO 104, with improved cage material (polyamide-reinforced brass).
